I believe so. I asked this question last month to this list, and got a positive answer. Anyways, one thing is certain: what Google Maps does with VML and transparent images on top of a tiled set of raster images,people routinely do with SVG in the webmapping context. Check carto.net for numerous examples of this... Anyways, here is a trivial example of dynamic overlays over maps (clunky and rough, but I hope you get the point that this already can be done... All the data points are delivered real-time from an external server. http://www.roitsystems.com/SVG-Widgets/navigation/ShipAutomation.svg It's kind of clunky, and the underlying image is statically located, but that is simply because I spent 3 days on this demo... And it works on any implementation that supports script access to the DOM or to the uDOM, and xmlhttprequest or GetURL. The key point I am attempting to make is that the community would be better served by interested developers supporting and extending existing SVG implementations rather than by going out on and starting Yet Another Implementation... Ask any SVG browser developer, and you will get the same answer: it's not that simple. The trivial stuff like static SVG is fine, but that's not enough, and is not SVG1.2 or SVGT1.2 compliant, so static implementations are really of no interest to anyone. And anyways, there are too many static SVG implementations to list. It took Mozilla 3 years toget to where they are today, and anyone who thinks they can do better from scratch is kidding themeselves. There are plenty of existing solutions out there... let's help the developers working on those implementations rather than making their task even harder by competing against them. Finally, if you want a feature you can't find in your favorite opensource SVG implementation, why not request a feature and get some people together to fund the work? A little financial sponsorship goes a long way in open source...
